I'm not into it at all. I'm a live and let live type of person as long as you don't hurt others and normally I wouldn't really care what types of acts others are into baring them being dangerous, exploitative or really sick, but anal sex fans, or at least a vocal segment of them, seem to be a really whiny, entitled, bitchy group of people that like incessantly pushing the performers until they get what they want. (Some interracial fans are as bad or worse.) I feel sorry for performers today more than ever. Not only do they have to work harder for less pay, but it seems like most of them can do nothing but get bitched at by a wide segment of people who view the industry they are in, and they just can't win no matter what they do.
Add to that it seems to the producers that more and more porn "needs" to have it today either because the producers and performers listen to or give too much consideration to those loud bitchy people for fear of limiting their careers. I don't buy that line of reasoning myself, but when there is a cutthroat business and so many people looking for what they think is the quickest easiest buck that's what you get. While that's bad on a more personal level it also limits what I'm willing to look at and buy. Even supposedly a site or movie has other non-anal stuff in it it's the equivalent of buying a plate of food where half of it is good and the other half is disgusting. Sure, theoretically I could just scoop off the half I don't like, but I don't like wasting time and money on stuff I don't like, and when it comes down to it I'm almost certain to not buy that plate of food in the first place because of the hassle.
